Have you ever ducked into a meeting you weren't supposed to, or stepped into the wrong showing at a movie theater? Sure you have. But lucky for you, the mishap wasn't captured on camera.

We can't say the same for Sen. Dan Coats, R-Ind., who wandered into a Senate Appropriations subcommittee hearing Wednesday and began asking the Treasury Department's witness a series of questions before a staffer informed him he was in the wrong place.

"I just got a note saying I'm at the wrong hearing," the Indiana Republican said. "I've got the right room number, but the wrong hearing. Well this is the first time this has ever happened to me."
